| 摘 要： | 在高温木炭床裂解炉上,对以木粉为原料的120Kw鼓泡流化床气化炉产生的气化气中的焦油进行了裂解研究,采用溶剂冷态捕集焦油和称重分析相结合的方法对裂解前、后的焦油含量进行了测量.结果表明,在高温木炭床上发生的木炭吸附焦油、焦油的高温裂解和木炭灰催化裂解焦油等一系列的物理化学过程,可有效降低燃气中的焦油含量,同时可以获得热值为5MJ/m^3的可燃气.

| Abstract: | In a high-temperature fixed bed burner with charcoal as bed meterial,experiments of tar destruction were performed in gasification process of a 120 kWh BFB gasifier with wood powder as feedstock.Tar was absorbed by cool solvent and analyzed by gravimetric method before and after tar destruction.The result shows that a series of physical & chemistry processes(e.g.tar obsorbed by charcoal,thermal destruction of tar and catalytic destruction of tar by ash of char) which occurred almost simultaneously in high temperature charcoal bed will effectively decreas the tar content in producer gas and a gas with about 5 MJ/m3 of LHV was produced at the same time. |
